I don't think it really helps to put Frontier up on a pedestal and that video watched with out rose tinted glasses is just a bunch of people talking about grand ideas.
There's not doubt there are a lot of talented guys and gals at Frontier but they've never attempted a game anything like FD before and its pretty clear from the state of the game that they've underestimated the challenges involved and are as a consequence releasing a game that is a long way from where it should be and in a state that is no where near the standard it should be. Some stuff in ED is great and you can see the link between what they are talking about in that video and what we find in game... Sounds design, visual design, visual FX. But much of it isn't anywhere near where they are talking about it being.
I want ED to be an amazing game as much as the next guy, but I'm also a realist and its not there yet, should not be being released yet and has gone down some fundamentally flawed design paths (dropping offline, no modding support, lack of narrative driven gameplay, homogeneous universe, far to easy and fast travel, too vast an inhabited space which is all the same, persistent online only universe that just dilutes our own efforts into nothingness with player and NPC actions.... I could go on).
I've gotten a reasonable amount of play out of the game so far and I'm sure I'll sink a few dozen hours in post launch. Certainly enough to feel like I got my moneys worth, but its not going to be a game I play for months let alone years, adjusted for time and tech its a pale shadow of its forbears. I'll play it, enjoy the good bits, get bored and move on. Maybe I'll check out the expansions but I didn't buy the pass so they'll have to work hard to pull me back.
